WELL-CASING.

Specification of Letters Patent.

Patented July 26, 1910.

Application filed September 24, 1909. Serial No. 519,439.

To all whom "it may concern:

Be it known that I, PAUL HARDY, a citizen of the United States, residingat lValnut Springs, in the county of Bosque and State of Texas, haveinvented certain new and useful Improvements in VVell-Casings, of whichthe following is a specification.

My invention relates to new and useful improvements in well casings.

Its object is to provide a sectional well casing, the sections of whichare adapted to fit securely one upon another, an annular seat beingprovided near the top of each section to receive the lower end of thesection above it.

Vith this object in view, my invention has relation to certain novelfeatures of the construction, an example of which is described in thefollowing specification, and illustrated in the accompanying drawingwherein Figure l is a view of the lower end of a section of the casing,and Fig. 2 is a sectional elevation of the casing.

Referring now more particularly to the drawing, wherein like numerals ofreference designate similar parts in all the figures, the numeral 1denotes a section of the well casing. The upper extremity of the sectionis reduced to the same diameter as the in terior of the casing, forminga neck 2. At the intersection of the neck 2 with the casing proper, anannular seat 3 is formed, which is adapted to receive the lowerextremity of a section superimposed 011 the section shown. The upperedge of the section shown is beveled downwardly and inwardly asindicated at 4-. The purpose of this is to deflect the lower extremitiesof the pipes which are lowered after the casing is in position, so thatthere will be no obstruction offered to the pipes as they are let downinto the well. The lower inner edge of the section is slightly beveledas shown at 5, so as to permit the lower end of one section to easilypass over the neck portion 2 of a section already in position in thewell.

I do not limit myself to any particular material of which to constructthe herein described well casing, as clay, cement, concrete, metal orother material may be used without departing from the spirit of theinvention as set forth in the following claims.

What I claim is:

1. A sectional well casing having its upper extremity reduced to adiameter equal to the inner diameter of the casing, and having anannular shoulder between the reduced portion and the casing, the upperinner edge of the casing being beveled.

2. A sectional well casing having its upper extremity reduced to adiameter equal to the inner diameter of the casing, and having anannular shoulder between the reduced portion and the casing proper,which forms a seat for a similar section of casing, the upper and lowerinner edges of the casing being beveled.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. 1 PAUL HARDY.
